At least eight cases of the mumps are now being reported on the IU Bloomington campus.
Mumps cases have also been reported at other Indiana colleges, but health officials say at this point, there does not appear to be any connection between the cases at Butler, IU-Bloomington and IUPUI.
Up to 30-percent of people who have mumps may not show symptoms, so it can be difficult to determine who may be infectious or how people may have been exposed.
Indiana State Health Department epidemiologist Pam Pontones says most of those who contracted mumps already had the MMR vaccine.
“With the MMR vaccine, up to 12-percent of people who received the recommended two doses actually can still get mumps,” Pontones says.
But she says the vaccine is still the best protection available. IU is offering another round of free MMR vaccinations Thursday.
